BMC013 Random Resonator, PCB + IC
Alters the timbre of oscillators
This is a somewhat minimalist module used to alter the timbre of an oscillator. There is a blend knob which lets the user select how much of the original oscillator is present, and a complexity knob controlling how complex the new timbres being added might be.
This circuit takes an incoming VCO signal and whenever the signal transitioned from negative to positive it triggers a series of short pulses. The Random Resonator selects amplitudes, lengths and the number of pulses completely at random (surprise!). A loop switch toggles whether the resonator will repeat the series of pulses at it's end or not. When the New button is pressed a new random series of pulses is generated. The complexity level of the new series of pulses depends on the setting of the complexity knob when the button is pressed.
